The PLEXUS can output up to 2 DMX universes in Stand Alone mode per device. If you need more than 2 DMX universes output, you can use several PLEXUS. The output of all PLEXUS can be synced.
The PLEXUS can output the DMX data via the included DMX ports or via Art-Net.

You can connect as many PLEXUS as you want in the Master/Slave Mode. The only limit is the amount of network devices you can add in your local network.
Every PLEXUS is able to output up to two DMX universes. That means the possible number of output universes in stand alone mode depends on the amount of used PLEXUS in the project.
